DISPENSING DEVICE FOR DENTAL ALLOY AND MERCURY Filed July 23, 1928 fife-05m Ck 4.4/51. 4/80 INVENTOR Patented June 24, 1930 P E OFFICE FREDERICK G. JELLISON, OF-BOWLEY, MASSACHUSETTS DISPENSING DEVICE FOR DENTAL ALLOY AND MERCURY Application filed July 23,1928. Serial No. 294,761.

This invention relates to a dispensing device for dispensing simultaneously two or more ingredients from containers holding the same, the general object of the invention being to provide a base to which the containers are attached, with a rotary shaft in the base having pockets therein, one for each contamer whereby when the shaft'is turned to a certain position, the pockets will be filled with material from the containers and then, by giving the shaft a half turn, the pockets will empty themselves into suitable outlet means so that the materials will fall into a container placed under the outlet means and the mixture will consist of certain amounts of materials from the first mentioned containers, according to the sizes of the pockets.

While the invention 'is mainly intended for use in dental laboratories and may be used for handling alloy and mercury, it will, of course, be understood that it may be used for other purposes;

Another object vide means for regulating more of the pockets.

A still further object of the invention is to provide an agitator for one or more of the containers, with means for moving the same as the shaft is rotated.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying draw- .ing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation showing one form of the invention.

Figure 2 is an end view thereof. Figure 3 is a top plan view. Figure 4 is a section on line 4-4: of Figure 2.

In these views, the numeral 1 indicates a base which is formed with a tapered bore 2 and with sockets 3 in its upper part for reof the invention isto prothe'size of one or e ceiving the lower ends of the containers 4:

which hold the materials to vbe dispensed. For instance, one containermay hold alloy and the other mercury. Aport 5 connects each socket 3 with the bore and an object port ,6 is formed in the lower part of the base under one of the ports 5, with a notch 7 in the wall of the port 6 which is located under the other port 5. A tapered shaft 8 is rotatably arranged in the bore and has a head 9, the inner face of which is grooved, as at 10, to receive acam ring 11. This shaft is formed with the cups 12, one for each container, these cups registering with the ports 5 when the shaft has been turned by the-fingers of the operator grasping the head 9. Thus some of the material in each container will pass through the port 5 into a pocket of the shaft and then by giving the shaft a half turn, the pockets will empty themselves into the port 6 and the notch 7 so that the two amounts of materials will pass into a container placed under the device. Thus a certain amount of each of two or more materials will be dispensed each time the shaft is turned. p

A set screw 13 is arranged in a threaded hole in the rear end of the shaft with its inner end extending into one of the pockets so that by adjusting this screw, the size of the pocket can be regulated. An agitator 14: is arranged in one of the containers 4: and is formed of wire coiled upon itself, with its limbs extending downwardly through the container with one limb bent and fastened to the base and its other bent and extending through a hole in the base, with its extremity engaging the cam ring 11 so that the agitator will be moved as the shaft is turned and thus the material in said container 4 will be agitated.

While the drawing shows the device with but two containers, it will, of course, be understood that the device can be made larger so that it can support a greater number of containers with their associated parts.

A screw 15 is connectedwith the base so that the device can be fastened to a suitable support.

It is thought from the foregoing description that the advantages and novel features 100 of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combi nation and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is A- deviceof the class described comprising a base having a bore therein and ports in its upper portion communicating with the bore and an outlet port in its lower part arranged under the other ports, containers supported by the base and in communication with the upper ports and a shaft rotatably mounted in v the bore and having ckets therein arranged to re 'ster alternate y with the upper ports and t e lower port durin the rotation of the shaft so that some of t e material in each container will drop into the pockets and then be discharged through the outlet port, an agitator in one of the containers having a part passing through a part of the base, a handle forming head on the outer end of the shaft and a cam on said head engaging said part of the agitator for moving the agitator when the shaft is turned.

In testimony whereof I aflix m signature.

FREDERICK G. JE ISON.
